Description

Technical Field

[0001] The invention relates to the technical field of body position adjustment equipment, and in particular to a body position adjustment device for patients with craniocerebral trauma. Background Art

[0002] The patient's condition is serious in the early stage after craniocerebral trauma, and they are unable to complete the change of body position independently. Therefore, correct positioning of the body in bed is very important. A good posture can make the patient feel comfortable and put the limbs in a functional position, which can prevent pressure sores and relieve limb contractures.

[0003] Common body positions for patients with craniocerebral trauma include lateral and supine positions. The lateral position is a position that the patient feels comfortable in, and this position also has the effect of counteracting spasms of the upper limb flexors and lower limb extensors of hemiplegia. It is usually achieved by bending the patient's lower limbs and lying on the side. The supine position is when the head is in a neutral position, with the elbows extended, the wrists dorsiflexed, and the fingers extended. Since the patient is unable to change body positions independently in the early stages, nursing staff are usually required to assist the patient in changing and replacing them. On traditional hospital beds, when changing from a supine position to a lateral position, medical staff are required to manually turn the patient's body over, and then manually bend the patient's lower limbs. This method is more labor-intensive and takes too much time each time. Nowadays, the beds that assist in turning over on the market are usually inclined beds, which assist medical staff in turning the patient's position more effortlessly. However, the legs cannot bend by themselves, and medical staff still need to manually assist in bending them, which is more time-consuming and labor-intensive.

[0019] refer to Figures 1 to 10 , a body position adjustment device for patients with craniocerebral trauma, comprising an n-shaped bed plate 1, a semicircular bottom plate 2, a fixing lever 3, a thigh placement plate 10, a calf placement plate 11, a protection rod 9, an operating mechanism, a tilting mechanism, a movable mechanism, a first flipping mechanism, and a second flipping mechanism; The lower ends of the two vertical plates of the n-shaped bed board 1 are respectively fixedly mounted with semicircular bottom plates 2, and the lower ends of the two semicircular bottom plates 2 are respectively mounted with fixed levers 3. The n-shaped bed board 1 is used to support the entire torso of the patient. The two semicircular bottom plates 2 will drive the n-shaped bed board 1 to tilt under the drive of the tilting mechanism described later to assist in turning over. The semicircular side surfaces of the semicircular bottom plates 2 will not form interference contact with the fixed levers 3 close to them during the rotation process. The middle parts of the upper ends of the two fixed levers 3 are respectively fixedly mounted with first connecting frames 301; The lower ends of the two semicircular bottom plates 2 are rotatably mounted in the first connecting frame 301 close thereto; Both semicircular bottom plates 2 are driven to rotate by a tilting mechanism; An operating mechanism is installed between the two fixed levers 3, and the tilting mechanism is driven to work by the operating mechanism; The second connecting frames 103 are fixedly installed on both sides of the middle part of the upper end of the horizontal board of the n-shaped bed board 1, and the first end of the thigh placing board 10 is rotatably installed between the two second connecting frames 103. The thigh placing board 10 is driven to rotate by the first turning mechanism. The thigh placing board 10 is used to support the thigh of the patient, and can drive the thigh of the patient to be lifted and bent under the drive of the first turning mechanism described later; The second end of the thigh placement board 10 is respectively fixedly installed with a third connecting frame 1001, and one end of the calf placement board 11 is rotatably installed in the two third connecting frames 1001. The calf placement board 11 is driven to rotate by the second flipping mechanism. The calf placement board 11 is used to support the patient's calf. When the thigh placement board 10 is bent under the drive of the first flipping mechanism, the calf placement board 11 will be bent at the same time under the drive of the second flipping mechanism, and the bending point is the joint connection between the patient's thigh and calf; The thigh placement board 10 drives the second turning mechanism to work by rotating; The first flipping mechanism is driven to work by the tilting mechanism; A plurality of protective rods 9 are movably mounted on both sides of the horizontal plate of the N-type bed board 1. The plurality of protective rods 9 are driven to move by a movable mechanism. When the N-type bed board 1 is tilted and flipped under the drive of the tilting mechanism, the protective rods 9 in the tilting direction will simultaneously be lifted toward the tilted side of the bed board to prevent the patient from falling off; The movable mechanism is driven to work by the tilting mechanism.

[0020] The tilting mechanism comprises a T-shaped slider 14, a fourth connecting frame 1401, a first connecting rod 4, a fifth connecting frame 102, and a first sliding rod 5; T-shaped slide grooves 302 are respectively provided at both ends of the top walls of the two fixed levers 3, and the horizontal plates of the T-shaped sliders 14 are respectively slidably installed in the four T-shaped slide grooves 302; The upper ends of the vertical plates of the four T-shaped slide blocks 14 slide through the vertical grooves of the T-shaped slide grooves 302 respectively, and the fourth connecting frame 1401 is installed; The first ends of the first connecting rods 4 are rotatably mounted in the four fourth connecting frames 1401 respectively; The two ends of the two vertical plates of the n-shaped bed board 1 are respectively installed with fifth connecting frames 102 that cooperate with the fourth connecting frames 1401; The second ends of the four first connecting rods 4 are respectively rotatably mounted in the fifth connecting frame 102 adjacent thereto; The inner walls of the two fourth connecting frames 1401 located on the same side of the n-shaped bed board 1 are fixedly connected by a first sliding rod 5; One of the first sliding rods 5 drives the first flipping mechanism to work by sliding; The first sliding rod 5 that drives the first flipping mechanism to work is driven to slide by the operating mechanism. The first sliding rod 5 that drives the first flipping mechanism to work starts to slide reciprocatingly under the drive of the operating mechanism, and in the process of sliding, drives the two first connecting rods 4 close to it to start to deflect up and down respectively. In the process of up and down deflection, the two first connecting rods 4 respectively drive the n-type bed board 1 to start to tilt up and down, and the two first connecting rods 4 located on the other side will deflect synchronously, and the first sliding rod 5 close to the two first connecting rods 4 on the other side will slide accordingly. In the process of up and down tilting of the n-type bed board 1, the semicircular bottom plate 2 fixedly connected to its two vertical plates starts to rotate around their respective rotation centers, thereby realizing the tilting of the n-type bed board 1, and due to the action of the operating mechanism described later, the n-type bed board 1 also has a certain locking function during the tilting process.

[0021] The operating mechanism includes a horizontal fixed rod 25, an expansion block 502, a threaded rod 26, and a servo motor 27; A same horizontal fixed rod 25 is fixedly installed between the two fixed levers 3, and a first sliding rod 5 driving the first flipping mechanism to work is movably installed on the outside of the horizontal fixed rod 25; An expansion block 502 is fixedly installed at the lower part of the middle end of a first sliding rod 5 close to the outer side of the horizontal fixed rod 25; The threaded rod 26 is installed through the internal thread of the expansion block 502, and the threaded end of the threaded rod 26 is rotatably connected to the front wall of the horizontal fixed rod 25; A servo motor 27 is installed at the other end of the threaded rod 26, and the output shaft of the servo motor 27 is fixedly connected to the threaded rod 26; The servo motor 27 is fixedly installed between the two fixed levers 3. When the servo motor 27 is started, the output shaft of the servo motor 27 begins to drive the threaded rod 26 coaxially fixed therewith to start rotating. The threaded rod 26 is a reciprocating screw. During the rotation, the reciprocating screw drives the expansion block 502 threadedly penetrated therewith to start reciprocating sliding. The first sliding rod 5 fixedly installed with the expansion block 502 now has the ability to reciprocate sliding. The first sliding rod 5 close to the servo motor 27 can drive the fourth connecting frame 1401 fixedly installed at its two ends to start moving during the reciprocating sliding process. The T-shaped slider 14 fixedly installed with the fourth connecting frame 1401 slides along the T-shaped slide groove 302 matched therewith, thereby limiting the sliding trajectory of the first sliding rod 5 and ensuring that it will not deviate and fall off during the sliding process.

[0022] The first flipping mechanism comprises a second sliding rod 20, a second T-shaped frame 19, a sixth connecting frame 2001, a second connecting rod 6, a third connecting rod 21, a third sliding rod 23, a sliding block 24, a first rectangular sliding block 22, and a fourth connecting rod 12; The upper ends of the horizontal plate of the n-shaped bed board 1 are respectively provided with rectangular through grooves 101, and first rectangular sliders 22 are respectively slidably installed in the two rectangular through grooves 101, and the lower ends of the two first rectangular sliders 22 are respectively slidably penetrated through the adjacent rectangular through grooves 101 and fixedly installed with the same third sliding rod 23; The first connecting shafts are fixedly mounted at both ends of the third sliding rod 23, and the first ends of the fourth connecting rod 12 are rotatably sleeved on the outer sides of the two first connecting shafts. The second connecting shafts are fixedly mounted on the front and rear side walls of the second end of the thigh placement board 10, and the second ends of the two fourth connecting rods 12 are rotatably sleeved on the second connecting shafts close thereto. A sliding block 24 is slidably mounted on the lower end of the third sliding rod 23, a third connecting shaft is fixedly mounted on the outer wall of the sliding block 24, and a first end of the third connecting rod 21 is rotatably sleeved on the outer wall of the third connecting shaft; The lower end of the horizontal plate of the n-shaped bed board 1 is fixedly mounted with a vertical rod of a second T-shaped frame 19, and rectangular grooves 1901 are respectively provided on the right walls of both ends of the horizontal rod of the second T-shaped frame 19; The second sliding rods 20 are slidably installed in the two rectangular grooves 1901 respectively; Sixth connecting shafts are fixedly mounted on the right walls of the upper ends of the two second sliding rods 20, and the first ends of the second connecting rods 6 are rotatably sleeved on the outer walls of the two sixth connecting shafts. The middle of the inner wall of the two first sliding rods 5 is respectively fixedly mounted with a seventh connecting frame 501, and the second ends of the two second connecting rods 6 are respectively rotatably sleeved in the seventh connecting frame 501 close thereto; The sixth connecting frame 2001 is fixedly mounted on the right side wall of the lower end of the two second sliding rods 20; The second end of the third connecting rod 21 is detachably and rotatably sleeved in one of the sixth connecting frames 2001; The two fourth connecting rods 12 respectively drive the second flipping mechanism to work by rotating. The user can connect the third connecting rod 21 to any sixth connecting frame 2001 on both sides according to the flipping direction requirements of the bed board, and the third connecting rod 21 can slide along with the sliding of the sliding block 24, and the sliding mode of the sliding block 24 does not need to be limited. When the third connecting rod 21 is fixed to one of the sixth connecting frames 2001, the sliding block 24 can be fixed, and the connection between the third connecting rod 21 and the sixth connecting frame 2001 can be achieved only by a detachable fixing pin. Figure 4When the third connecting rod 21 and the sixth connecting frame 2001 are fixed, as the n-shaped bed board 1 tilts, the second T-shaped frame 19 fixedly connected thereto can be tilted synchronously with the bed board 1. When the second T-shaped frame 19 gradually approaches the ground during the synchronous tilting process, the first sliding rod 5 close to its tilted end will slide in the direction away from the second T-shaped frame 19, and drive the second connecting rod 6 to start deflecting downward during the sliding process. Since the second connecting rod 6 is rotatably connected to the second sliding rod 20 during the deflection process, the second sliding rod 20 starts to move under the pull of the second connecting rod 6. The first sliding rod 5 close to the tilted end of the n-shaped bed plate 1 slides in the direction close to the second T-shaped frame 19, and the second connecting rod 6 matched therewith deflects upward, and the second sliding rod 20 close thereto begins to slide upward along the matched rectangular groove 1901, and the second sliding rod 20 sliding downward at this time close to the inclined end will drive the third connecting rod 21 close thereto to start deflecting downward, and the third connecting rod 21 pulls the third sliding rod 23 to start sliding forward during the downward deflection process, as shown in FIG. Figure 5 As shown, the third sliding rod 23 will respectively drive the fourth connecting rods 12 on both sides to start to deflect forward during the forward sliding process. The fourth connecting rods 12 on both sides will respectively drive the thigh rest board 10 to start to rotate upward around its rotation center during the forward deflection process. The thighs placed on the thigh rest board 10 will be lifted up synchronously at this time. During a tilting cycle of the n-type bed board 1, the thigh rest board 10 will be lifted up and then flattened again as the n-type bed board 1 flattens.

[0023] The second flipping mechanism comprises a fifth connecting rod 13, a fourth connecting shaft, and a fifth connecting shaft; Fourth connecting shafts are fixedly mounted on the outer walls of the middle ends of the two fourth connecting rods 12, and first ends of the fifth connecting rods 13 are rotatably sleeved on the outer walls of the two fourth connecting shafts. A fifth connecting shaft is fixedly mounted on the front and rear side walls of the right end of the calf placement plate 11; The second ends of the two fifth connecting rods 13 are respectively rotatably sleeved on the outer wall of the fifth connecting shaft close thereto, Figure 6When the thigh support plate 10 rotates upward, the fourth connecting rods 12 on both sides will also deflect upward. During the upward deflection, the angles between the fourth connecting rods 12 on both sides and the fifth connecting rods 13 close to them become smaller. Since the rotation center of the calf fixing plate 11 is fixed, as the angle between the fourth connecting rod 12 and the fifth connecting rod 13 becomes smaller, the calf fixing plate 11 also rotates upward. During the upward rotation of the calf fixing plate 11, the patient's calf will be supported to rotate. As the n-type bed board 1 turns flat after tilting, the calf fixing plate 11 and the thigh fixing plate 10 turn flat synchronously. At this time, the patient turns over after the n-type bed board 1 tilts, and the upper and lower legs are in a bent state after turning over, making the patient's side-lying posture more comfortable and reducing the workload of medical staff in assisting the turning.

[0024] The movable mechanism comprises a mounting platform 7, a first T-shaped frame 15, a mounting rod 8, a second rectangular slider 17, a first fixed link 18, and a second fixed link 16; The lower end of the horizontal plate of the n-shaped bed plate 1 is fixedly mounted with a vertical rod of the first T-shaped frame 15, and the first T-shaped frame 15 is mounted on the left side of the second T-shaped frame 19; The two ends of the crossbar of the first T-shaped frame 15 are respectively vertically mounted with mounting rods 8, and a plurality of protection rods 9 located on both sides of the crossbar of the n-shaped bed board 1 are respectively slidably arranged between the mounting rods 8 close thereto; The lower ends of the plurality of protection bars 9 on the same side are fixedly mounted with the same mounting platform 7, and the two mounting platforms 7 are movably mounted below the mounting bars 8 close thereto; A second rectangular sliding block 17 is rotatably mounted on the left side walls of the two mounting platforms 7; A first end of a first fixed link 18 is fixedly mounted on the middle portion of the inner wall of the fixed lever 3 close to the two mounting platforms 7 via a fixed shaft; The middle end of the second fixed link 16 is fixedly mounted on the right wall of the second end of the first fixed link 18, and the second fixed link 16 is arranged parallel to the horizontal board of the n-shaped bed board 1; A rectangular slide groove 1601 is provided on the right wall of the second fixed link 16, and two second rectangular sliding blocks 17 are slidably installed in the rectangular slide groove 1601; The two first sliding rods 5 are respectively slidably mounted on both sides of the first fixed link 18, Fig. 9In the process of tilting, the n-shaped bed board 1 also drives the first T-shaped frame 15 fixedly connected to its lower end to start tilting. In the process of tilting, the first T-shaped frame 15 also drives the two mounting platforms 7 to start tilting respectively, and the tilting direction is one side high and the other side low, and the low side is close to the tilting direction of the n-shaped bed board 1. Since the second fixed link 16 and the first fixed link 18 are fixed, the rectangular slide 1601 is also fixed. The two second rectangular sliders 17 located in the rectangular slide 1601 will slide to a certain extent with the tilting of the first T-shaped frame. Since the two second rectangular sliders 17 are respectively rotatably connected to the mounting platforms 7 close to them, the tilting of the first T-shaped frame 15 will not be constrained. Instead, it will ensure that the two mounting platforms 7 will not fall off due to gravity. The technical effect is that the mounting platform 7 close to the ground will approach each other with the mounting rod 8, and the mounting platform 7 will drive a number of guardrails 9 to pass through the mounting rod 8 to form a relatively high effect of the guardrails 9 at the tilted end, which can effectively prevent the patient from falling off during the turning process.

[0025] Implementation method of the present invention: Place the device on a horizontal plane, and the patient lies on the upper end of the horizontal board of the n-shaped bed board 1, with the thigh placed on the upper end of the thigh placement board 10, and the calf placed on the upper end of the calf placement board 11. The length of the thigh placement board 10 meets the requirements of patients with normal leg lengths. It is not suitable for patients who are too tall or too short. The bending of the thigh and calf joints is aligned with the rotating connection between the thigh placement board 10 and the calf placement board 11. The patient's initial lying position is supine, and the equipment is as follows: Fig.10 As shown in A, when turning over is required, the medical staff can operate the servo motor 27 to drive the reciprocating screw to rotate, and the switch controlling the servo motor 27 can be set at the edge of the bed near the medical staff, so that the medical staff can observe the patient in time during the turning over process; When the reciprocating screw is rotating, the n-shaped bed board 1 starts to tilt to one side, and in the process of tilting, the thigh placing board 10 and the calf placing board 11 start to tilt synchronously. Since the patient's body lies flat on the n-shaped bed board 1, the patient starts to turn over synchronously with the tilt of the n-shaped bed board 1, and in the process of turning over, the thighs and calves start to bend synchronously with the thigh placing board 10 and the calf placing board 11, and several guardrails 9 close to the bending side rise relatively, which plays an effect of preventing the risk of the patient turning over and falling off, and finally forms the following Fig.10 In the state shown in B, as the reciprocating screw rod rotates back, the n-type bed board 1, the thigh placement board 10 and the calf placement board 11 will begin to reset to Fig.10 State A, during this process, the patient has completed turning over and his legs can be bent after turning over, making the side-lying position more comfortable; When the patient needs to turn over to the other side, it is only necessary to remove the pins on the third connecting rod 21 and the sixth connecting frame 2001 previously connected, and use the pins to rotatably connect the third connecting rod 21 and the sixth connecting frame 2001 on the other side. During this process, the sliding block 24 will move synchronously with the movement of the third connecting rod 21 and be limited when the third connecting rod 21 and the sixth connecting frame 2001 on the other side are fixed; After installing the third connecting rod 21, repeat the above operation.

[0026] The first turning mechanism of the present invention can automatically support the patient's thigh as the N-shaped bed board turns over, so that the patient's thigh and calf can bend automatically. The bent calf can be placed on the calf support board, and the calf support board will bend synchronously with the thigh support board. After the patient completes the turning, he can maintain a side-lying posture with bent lower limbs, avoiding the medical staff's laborious assistance. When the N-shaped bed board of the present invention is tilted, the movable mechanism will also synchronously drive the protective rod to rise from the tilted direction to avoid the patient rolling off the bed, thus having a strong sense of safety.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
